请帮助分析一下谢谢
A person who believes that he is
incapable will not make a real effort, because he feels that it would be
useless. He won't go at a job with the confidence necessary for success. He is
therefore 21 to
fail, and the failure will strengthen his belief in his incompetence.
Alfred Adler, a
famous doctor, had an experience 22 illustrates this. When he was a small boy, he
was poor at arithmetic. His teacher got the idea that he had no ability in
arithmetic, and told his parents what she thought that they would not expect
too much of him. 23 this way, they too developed the idea,
"Isn't it too bad that Alfred can't do arithmetic?" He accepted their
mistaken estimate of his ability, felt that it was useless to try, and was very
poor at arithmetic, just as they expected.

One day Adler succeeded in solving a problem which 24 of the other students had been able to solve.
This gave him confidence. He rejected the idea that he couldn't do arithmetic
and was determined to show them that he could. His new 25 confidence stimulated him to go at arithmetic
problems with a new spirit. He now worked with interest, determination, and
purpose, and he soon became extraordinarily good at arithmetic.
